Sister District Whitepapers

SDAN’s white papers are meant to provide enough detail about our studies to allow others to completely understand our findings and replicate our methods. These white papers provide more rationale behind the studies, as well as more detail about methods and analyses employed, compared to our blogs and short reports. They are perfect for fellow scientists and number crunchers, as well as anyone who is curious about learning more about what went into a particular study. White papers are published as they are available.
